G750JZ - Boot Failure

[KazariK]

Hey all..

So I have an issue with my new G750JZ laptop..
A few weeks ago I ran into this problem but thought it was just doing an update but now I believe this is a REAL ISSUE and havent seen any other posts on this (maybe I am just not searching correctly).

The model I have came with the 500 gig ssd and 750 hd.
During boot up from a shut down, the laptop FAILS to reboot.. I get the harddrive light and Wifi light flashing back and forth. I am suspecting something has gone bad with the SSD. It DOES reboot ONCE in a blue moon and I had it running for a few days and I came home yesterday, my FIRST day I have had time to sit down and talk to Tech support and as I sat down at the laptop it flashed up a notice that it was about to reboot in 5 seconds for an update and then well.. You get the idea.. It hasnt restarted since.. I completely turn it off and tried to reboot, nothing, took out battery, powered down for a day, same thing.. I have some tech experience so I have some ideas on what to do, but this has me stumped..

Is this an issue with these models? Or just something with mine?

While I really do appreciate the reply, this isn't about a "normal" bios flash. This thread is about an emergency recovery flash, done on notebooks that will not start up at all, hence there is no ability to access the bios. At all. The notebook does nothing. So no EZFlash.

The only way to recover from this is to insert a usb drive that has the bios file on it that you want to flash, then hold control-home then power on. At that time, the filename is read from the USB stick. And if it isn't named exactly right, it won't be recognized.

I am attempting to find out what the exact file name must be for the file to be recognized.

What program are you opening when you do this procedure...……..EZFlash!

Looks like you need to establish what model you have. G750JZ or G750JZA. You don't know?

Try all combinations. Keep in mind, you have two different BIOSs, depending on the model, BIOS G750JZAAS.210 (G750JZA.bin and G750JZAAS.bin) and BIOS G750JZAS.210 (G750JZ.bin and G750JZAS.bin). Don't mix them up.

G750JZ.bin
G750JZAS.bin
G750JZA.bin
G750JZAAS.bin

You do know you have to hold down the buttons for about a minute?

Thanks again for the additional help! Here's what happens...

1. Put the usb drive in the laptop
2. While holding control and home, press the power button.
3. Initially, the usb drive lights up, as if it's being read
4. I keep holding down the control and home buttons
5. Eventually, the usb drive light goes out
6. The disk and wifi lights on the laptop start to flash alternately... Which is what it does during a failed boot

I'm not getting any information displayed on the screen at all.

Unfortunately, the Product Registration Screen for my laptop just shows that it is a "G750JZ" and doesn't provide any additional information. I'm using the bios file provided by the Product Registration Screen. The filename, when downloaded, is "G750JZAS.210"

Edit: Forgot to say that I'll try the filenames suggested, thank you!

Have you unplugged the laptop from the charging brick, removed battery, held power button on for a couple minutes? Install battery, attach charging brick, normal power up?

As a last effort, remove CMOS battery from motherboard Replace the CMOS battery.

If that doesn't change anything, then get a RMA from ASUS and return the laptop to ASUS for repair.

Looking on the Internet, there seems to be many such problems with the G750xx model laptop.

Answer to first question: I've literally done this a hundred times now.

Answer to second question: I think that's going to be my next step.

And yes, it seems like every G750 owner ends up dealing with this *exact* issue at least once. Multiple users have said they've had to do this procedure numerous times. : /

Thanks again for the help, jdfrench3, much appreciated.

Seriously considering just buying a replacement motherboard from ali-express.

One final thought on this whole situation...

This emergency bios recovery technique really should have been included in the official User Guide documentation included with the laptop. Whoever wrote the User Manual should be fired for not including this vital information.

Not only would it have kept a large number of laptops from being returned to ASUS (which, of course, costs ASUS money), it would have greatly enhanced the user's experience of using the laptop, and would have avoided un-necessary user frustration.

Additionally, this issue is a very wide problem; pretty much every owner of the G750 series of laptops will experience this problem at some point. And it's an engineering flaw. If a guy returned his laptop under warranty because of this problem, ASUS would replace it with a laptop with the same engineering flaw, ensuring that at some point, the user will experience the exact same issue. The way that ASUS has (or rather, hasn't) handled this issue speaks volumes.

Personally, I'm done with ASUS hardware, and when my G750JZ finally bites it, it'll be replaced with a competitor's machine.

I totally understand your frustration.. LIKE A LOT! Seriously, Ive had to do this emergency restore more times then I would ever want to count and in all the computers Ive owned in my lifetime (which I am sad to say has been fairly long), the ROG is the ONLY device Ive ever had this happen on...
I come back from time to time to get the files or instructions again when it happens. Honestly in a year, it probably happens at least once, maybe twice.. My ROG is my backup now that I have my work notebook, but its still my personal primary. I wont be buying another ROG product because of that issue.

The thing that upset me the most was when I did reach out to ROG customer service oh so many years ago I was told this wasnt a THEM problem but a Microsoft problem... Funny, Ive had lots of devices running microsoft over the years and none have ever had this issue. Seems like a ROG issue to me..

Im back here today because sure enough I went to use my computer and it wouldnt boot.. So now I need to make a new boot usb... Im thinking about getting some velcro tape and just taping the damn usb to the computer, so the next time it happens Ill know exactly where the USB is.. ugh...

So I ended up downloading another bios, for the G750JZA, and it worked. I'm still not sure what the exact filename is, as I had four differently named bios files on the usb stick.

Anyway, much thanks to everyone in this thread. You guys got my brick working again.
